Fulltime RV'ing-Truck camper; built-in washer/dryer Question

If I was full timing in a TC, I would need to tow an enclosed support trailer for all the bulky/heavy stuff you don’t want in the truck or camper. That’s where I would put a small washer/dryer pair or a combo unit.

I just can’t see the need to have something like that IN the truck camper itself.
